Tilling the soil with copper sulfate in the spring for tomatoes

Soil preparation

Here's what's important when landing:

• The soil is preferably sandy or loamy with an acidity of about 6 pH.
• In spring, the earth loosens and fills with oxygen.
• Disinfectants are added against fungal and viral diseases, insect eggs and fungal spores.

Soil suitable for gardening contains pathogens of fungal diseases. Therefore, it is important to prevent late blight disease in vegetable crops, destroy diseased bushes in a timely manner and disinfect the soil.

Do I need to process garlic before planting?

Experts recommend treating garlic bulbs and cloves with special preparations before planting, which will provide good protection against pests and diseases. After such treatments, the germination rate of planting material is almost one hundred percent.

However, you need to know which preparations are best used for winter and which for spring garlic:

1. Solutions of salt and copper sulfate
   can protect against various diseases. They can be used to treat both spring and winter varieties.
2. disinfects planting material that may contain bacteria and fungal spores. Potassium permanganate also promotes root formation. Used to treat teeth both in autumn and spring.
3. Ash infusion
   is intended to saturate seeds (onions) with microelements. After treatment with ash infusion, shoots appear faster, so it is used only for planting in spring.
4. Fitosorin-M
   is a drug of natural origin, which contains spores of soil bacteria. With its help, the safety of teeth is increased, which, after treatment with Fitosporin, will be protected from fungal and bacterial diseases. You can soak winter and spring garlic in the solution of the drug.
5. Maxim
   is a drug whose effect can be compared to antibiotics. Suitable for spring and autumn plantings.

1. To plant before winter, garlic is soaked in a rich dark solution of potassium permanganate for only 1-2 minutes.
2. In spring, planting material is kept for 10-12 hours in a slightly pink solution of potassium permanganate.

To make it convenient to soak the teeth and not have to fish them out of the solutions, they can be placed in a fabric bag.

How to disinfect soil with copper sulfate

Copper sulfate is the most popular and inexpensive means of combating tomato diseases in gardening. Another name is copper sulfate. It is a blue powder that gives the water a bright color. Sold in hardware stores in packs of 500 g.

Product packaging

Treatment of grapes with copper sulfate in spring

The substance should be stored in a dark, dry place, used for its intended purpose and not used after the expiration date.

This is a universal fungicide with astringent, antiseptic and disinfectant properties. Tilling the soil with copper sulfate in the spring for tomatoes is the basis for a healthy harvest.

On a note. Copper is an important trace element; if it is deficient, tomato leaves curl and the stem bends to the ground. Due to decreased immunity, late blight may appear.

In early spring, the area is cleared of plants and rotted leaves, the soil is dug up and loosened. At the same time, it is undesirable to leave lumps - the soil should be light and saturated with oxygen.

Then each bed should be treated with a solution of copper sulfate and water. A bucket of liquid will require 5 g of copper sulfate.

Important! Seedlings can be planted no earlier than a month after treatment with copper sulfate.

Benefits of using vitriol:

• Easy to use.
• Affordability.
• There are no side effects if the dosage is followed.
• Bacteria do not adapt to the product.

How it helps:

• Protects against viral diseases.
• Destroys fungal spores and insect larvae.
• Increases the immunity and frost resistance of the plant.

The use of copper sulfate for tomatoes is effective against the following diseases:

• root rot,
• transporosis,
• late blight,
• root beetle,
• downy mildew.

Instructions for use:

• Before starting work, put on rubber gloves and goggles. After finishing the procedure, wash your hands.
• Keep the prepared suspension away from children and animals.
• The solution is not stored longer than 5 hours; it is used immediately.
• Use a solution with a strength of up to 3%.
• Non-metallic utensils are used, preferably glass. You can no longer drink or eat from it.
• Before use, the solution is filtered and poured into spray bottles.
• Fill the hole a day before planting the seedlings.

Consumption is 10 liters per 1 m2.

Mixture for soil

If you exceed the norm or concentration, burn marks will appear on the tops, the greens will turn black, and the stem will stop growing. Using a smaller dose will not have the desired effect. It is important to dilute the mixture according to the recommendations on the package.

Unused liquid should not be poured into a river or stream; the chemical must be disposed of with care.

Preventive measures are carried out no more than once every 5 years. Otherwise, the balance of sulfur and copper content in the soil is disrupted, and toxins accumulate.

How to prepare a solution for treatment:

• For 1 liter of warm water, 100 g of the substance is required. The solution is diluted with another 10 liters of water. The resulting suspension is a 1% solution of copper sulfate.
• For 1 liter of warm water use 200 g of blue powder. Also dilute 10 liters of water. The resulting solution contains 2% copper sulfate.

How to prepare a working mixture

Excess copper in the soil has a negative effect on plants (growth slows down, ovaries and leaves fall off). Therefore, it is important to use copper sulfate correctly. The soil is most often treated with a 1% working solution, which is prepared according to the standard scheme:

• 100 g of powder is diluted with several liters of water heated to 45-50 ° C;
• pour the concentrated solution into a 10-liter container;
• The dishes are completely filled with water, stirring thoroughly.

When working with the substance, containers made of plastic and glass are used. It is recommended to dilute the drug before use.

How to get rid of late blight using copper sulfate

Spraying apple trees with copper sulfate in spring

Late blight is the main enemy of gardeners. Having hit one plant, it quickly moves with gusts of wind to all other bushes. The leaves are the first to suffer, followed by the base of the plant and the fruits. Within a week there is a risk of losing 80% of the crop. If you do not treat the vegetable crop with a fungicide in time, you will not have to enjoy homemade tomatoes.

Signs of late blight:

• The appearance of a bluish coating on the leaves.
• Brown marks spread across the leaves.
• The tomato becomes deformed, changes color and rots.
• The fruit gives off an unpleasant, pungent odor.

Fungal disease affects tomatoes for the following reasons:

• Frequent rains - longer than 3 days - create high humidity.
• Temperature jumps.
• Densely planted bushes. The disease often appears in greenhouses where there is insufficient ventilation. It will appear as brown spots on leaves, fruits and stems.

To protect yourself as much as possible from late blight, they fight in the early stages. If a fungus is suspected, the soil should be treated with a 0.5% solution, dose - 50 g per 10 liters.

Preparation of the solution

The copper sulfate solution is prepared in two steps:

1. Preparation of the mother solution.
2. Dilution to required concentration.

The stock solution is prepared as follows:

1. Take 100 g of crystalline sulfate.
2. In a plastic container, vitriol is poured into 1 liter of hot (at least 40 degrees) water.
3. The solution is thoroughly mixed until the crystals are completely dissolved.
4. If necessary, the finished mixture is filtered through cheesecloth to remove undissolved crystals and other impurities that may subsequently clog the sprayer nozzles.

The preparation of the mother solution should be carried out only in plastic, wooden or, in extreme cases, enamel containers. The vitriol solution interacts unpredictably with exposed metal and can cause the formation of additional iron salts (especially if the original raw material is poorly purified at the factory).

The resulting stock solution is diluted to the required concentration:

• For 1% – 1 liter of mother solution per 10 liters (1 bucket) of water.
• For 2% - 2 liters per bucket of water.
• For 3% - respectively 3 liters.

If you are preparing a solution of low concentration, you can do without a masterbatch. In this case, vitriol is diluted directly in a bucket of warm water in the following proportions:

1. For soaking seeds – 1 g per 10 l (concentration 0.01%).
2. To disinfect the above-ground parts of tomatoes – 10 g per bucket (concentration 0.1%)

It is best to dilute vitriol in warm (at least 20 degrees) water; in extreme cases, you can use settled water at street temperature. The softer the water, the better the drug dissolves, so if possible, you should use pre-collected rainwater.

The vitriol solution is not stored for a long time, so it is diluted immediately before use. If it was not possible to carry out the treatment immediately, and the liquid has stood for more than 6 hours, it is better to pour out the solution and prepare a fresh portion.

If Bordeaux mixture is being prepared, the dilution recipe will be as follows:

1. 100 g of vitriol is diluted in a small amount of warm water. To do this, water is poured into a plastic container with powder in a thin stream until all the vitriol has dissolved.
2. When the mother liquor is ready, more hot water is added until the total volume reaches 5 liters.
3. A suspension of lime is prepared in another container. To do this, 150-200 g of finely ground lime is thoroughly mixed in 5 liters of hot water until a white, milk-like liquid is formed.
4. A solution of copper sulfate is poured into the prepared lime suspension in a thin stream. The resulting mixture should be stirred, avoiding the formation of sediment.

You need to pour the vitriol solution into the lime suspension. In no case is it the other way around, since the concentration of the finished mixture may drop.

The resulting Bordeaux mixture must be used immediately: lime does not dissolve in water. If you let the mixture sit, small particles will settle to the bottom and the mixture will lose its beneficial properties.

The consumption of the finished mixture depends on what operation is being performed:

• When disinfecting soil known to contain late blight - 10 liters of 3% solution per 1 sq. m beds. But such processing should be carried out no more often than once every 5 years.
• When preventing late blight - 1 liter of solution with a concentration of 1% per 10 square meters. m beds.
• When soaking seeds - depending on their quantity. In this case, the mixture is practically not consumed.

If you are in doubt about the correct dosage, it is better to reduce it. Excessive concentration is dangerous.

Root and foliar treatment at different stages of cultivation

Treatment of cherries in spring against diseases and pests

During the preparation of planting material. After dressing with potassium permanganate, the seeds are enriched with microelements. To do this, mix 500 ml of hot water, 20 g of ash and 1 g of copper sulfate. The solution is kept in the refrigerator for 3 hours.

When planting seeds for seedlings. During this period, it is important to irrigate the soil for seedlings once. Use a 3% vitriol solution. This will destroy fungal and blackleg spores. Store-bought mixture should not be disinfected.

Treatment

During the period of picking seedlings. The soil is moistened with copper sulfate. Then the plantings are placed in a separate container. At this stage, only a 1% copper sulfate solution is used.

During planting in the greenhouse. The temperature should be no lower than 5 degrees. Each hole is watered with liquid. Don’t forget about adding fertilizing and mulch. Nightshade crops do not like acidic soil. To reduce the pH level, dilute Bordeaux mixture: mix 300-400 g of copper sulfate and 5 liters of water. In a separate container add 300 g of lime milk and 5 liters of water. Both mixtures are combined in a 1:1 ratio.

During the appearance of fruits. In mid-June, the bushes are sprayed with a 0.1% solution so as not to burn the fragile leaves.

After the harvest. At the end of the season, the greenhouse structure is washed even in the most inaccessible places and the soil is disinfected.

Additional Information. Do not be afraid to plant a tomato after a cucumber - these crops absorb various useful substances from the soil.

Characteristics of the drug

Copper sulfate is an inorganic substance in the form of light blue crystals. Water, which dissolves this copper sulfate salt well, also turns the same color.

To combat tomato diseases, specialized stores offer copper sulfate in plastic (less often glass) containers with a capacity of 100 to 500 grams. The product is stored in the absence of light and high humidity to avoid loss of physical and technical characteristics.

Spraying tomatoes

For disinfection of plants, the growing season is chosen - early spring. In this case, the procedures should be completed before the ovaries appear - 60 days. Otherwise, toxins will accumulate in the fruits. However, if you use Bordeaux mixture, the aggressive effect is reduced. The disadvantages include the appearance of blue spots on the leaves.

If you add laundry soda to copper sulfate instead of lime, the solution does not have to be filtered. All substances will dissolve and will not clog the nozzle hole. The product is also effective against fungal diseases and is easily washed off with clean water. At the same time, the process of photosynthesis is not disrupted and the appearance of the bushes is not spoiled.

On a note . To test the acidity, place an iron nail in the liquid. If there are traces of rust on it, you need to add soda and stir thoroughly.

Suitable times of day are considered to be morning before 9 o'clock or evening after 20 o'clock.

For the procedure, choose calm weather and irrigate each bush with 3 liters of the mixture. The leaves will be covered with a thin film.

In dry summers, plantings are no longer sprayed until August.

In the rainy and cool season, repeat the treatment every 2 weeks.

Methods of application

In the spring, every summer resident begins to think about upcoming work on the site. Copper sulfate becomes an indispensable assistant. When diluting the solution, you must follow the instructions.

Watering

It is better to water plants in the evening

To treat the soil, use a 3% solution. It is obtained by diluting 30 grams. drug per 1 liter of water. The resulting liquid should be watered the soil a week before planting or the soil for seedlings. Consumption rate 2 l/m². This is done to disinfect the soil from various types of fungi. Watering the beds is done in the spring in dry weather, preferably in the morning or evening.

Dry application

The drug is also applied in dry form as a microfertilizer to soils that are poor in organic fertilizers and humus. Apply 1 gram per 1 m². dry powder. Large amounts of copper negatively affect plant roots and their growth. The procedure is carried out once every 5 years (for poor soils - once a year).

Tatyana Orlova (candidate of agricultural sciences):

On acidic soils, copper is bound by soil acids into insoluble and therefore inaccessible complexes for plants. It is better to use foliar application of copper-containing preparations on the leaves.

Spraying tomatoes

Copper sulfate is used for tomatoes to destroy the late blight fungus. This disease appears as dark spots on the leaves and stems, and then on the fruits. For high efficiency, it is recommended to process tomatoes according to the following scheme:

1. Treating the soil or area before planting.
2. Spraying plants during the growing season.
3. Spraying fruits.

The first procedures are carried out before sowing seeds or planting seedlings - you need to treat the soil or area with a 1% solution. Watering the area should not be done in rainy weather. If these steps were missed, then after planting, spray with 0.1% copper sulfate.

Treatment of homemade tomatoes with copper sulfate is carried out in dry, windless weather in the morning or evening close to sunset. You need to spray the leaves and stems; do not water at the roots.

You can also spray tomatoes with Bordeaux mixture. This is the same copper sulfate, but together with slaked lime. The finished powder is sold in stores and is cheap. The main difference between Bordeaux mixture and copper sulfate is that the presence of lime makes the solution less aggressive and reduces the likelihood of burns. Copper sulfate on domestic tomatoes has a shorter useful life than on other crops. The last treatment is carried out 8 days before harvest.

Tatyana Orlova (candidate of agricultural sciences):

The advantage of Bordeaux mixture over pure copper sulfate is that lime acts as an adhesive in the mixture. Copper sulfate is easily and quickly washed off from the leaves even with light rains, and Bordeaux mixture is more resistant to them. If prolonged rains are expected, it is better to use Bordeaux mixture to protect plants.

Basic recommendations

It is easier to do prevention than to eradicate a disease. In addition to disinfecting the soil and plants, the greenhouse should be kept in almost sterile conditions.

After harvesting, the structure is washed.

During the summer season, old tools and equipment are not brought inside.

It is advisable to clean your shoes upon entry. A mat placed in front of the door, disinfected with copper sulfate, will help with this.

Advice! It is preferable to choose tomato varieties with immunity to fungal diseases.

To prevent or slow down the appearance of late blight, preventive measures are taken at all stages of planting tomatoes. This applies to the disinfection of the greenhouse, soil, roots and bushes of the plant. If the disease has manifested itself in full force, it is important to know the weather forecast. After the temperature drops to 15 degrees and precipitation falls, the tomatoes are sprayed with a solution of copper sulfate.

Why is the soil treated with copper sulfate?

Fungal diseases, rot, rust, late blight, fusarium, and scab cause significant damage to plant crops. If the soil is not disinfected before planting, the yield may decrease significantly.

It is copper sulfate that is used to disinfect soil. The drug also effectively destroys gnawing and sucking pests and helps increase plant resistance to diseases. The activity of the substance increases in alkaline soils.

Greenhouse treatment

If you are going to treat greenhouses, pay attention to all the details.

First, remove plant tops, ropes and other unnecessary equipment from the closed ground. Burn them to protect further plantings from viruses and bacteria.

Inspect the greenhouse for damage and cracks. They are sealed with sealant.

Technology

Clean the material that covers the greenhouse. To do this, use a regular soap solution. This procedure removes all remaining dirt. If there were metal parts in the greenhouse, they are washed with food vinegar (90 ml per 5 liters of water).

If scratches are detected, they are primed and coated with paint.

According to the instructions, dilute copper sulfate with water (300 g of substance per 10 l). All wooden parts are impregnated with the solution using a construction brush.

What is late blight

Late blight (lat. phytophthora) is a genus of oomycete fungi that causes late blight . More than a hundred species of this pathogen are known, affecting coniferous and deciduous trees, raspberries, and strawberries. Summer residents are familiar with late blight of tomatoes and potatoes.

Fungal spores remain in the soil, on tops and weeds, in seeds and remain viable for 3-4 years even in harsh climatic conditions. Late blight spreads from area to area on the soles of shoes, and is carried by wind and rain several kilometers from the source of infection. Spores are activated at moderate temperatures (15–20 °C) and relative humidity above 75%. Phytophthora requires drip moisture for germination.

In central Russia, late blight begins to appear in late July - early August . This is facilitated by cold weather with prolonged rains, sudden temperature changes during the day, causing heavy dew and fog.

3-4 days after infection, signs of disease appear on tomato plants.:

• dark spots without clear boundaries on leaves and stems that quickly grow and merge together;
• depressed brown spots of irregular shape on the fruit;
• after 2-3 days, a gray coating is visible on the surface of the spots - the sporulation organs of the fungus.

On a note. In late blight, the rot is hard (dry), in contrast to putrefactive lesions caused by bacteria and other fungi.

Why is it dangerous for tomatoes?

A particular danger of late blight is its rapid reproduction . After only 3-4 days, all the plants in the garden are affected. The bushes darken and wither.

Crop losses can be catastrophic . Fruits affected by rot are not suitable for food either fresh or for preservation.

Pathogen spores accumulate in the soil , threatening future tomato plantings.

Correct concentration

At first glance, it may seem that making a solution from this drug is very easy, but in fact the process requires experience and a lot of knowledge about the diseases that can affect the bush. Let's look at how to dilute copper sulfate in different cases.

A 1% solution is sufficient for surface treatment. This means 10 grams per 10 liters of water. The powder must be mixed in a large container, then poured into spray bottles and sprayed on the surface. This will allow the substance to be distributed most effectively throughout the site.

When wondering how to treat tomatoes with copper sulfate against late blight, you need to understand that spraying should under no circumstances be carried out during the daytime.

Considering the fact that at the slightest violation of the proportions there is the possibility of literally burning the bush. Direct sunlight that falls on a still fresh preparation will have virtually the same effect.

That is why treatment is carried out, as a rule, in the evening, when the sun is already setting, there is enough time for the drug to absorb and dry.

When considering the question of how to dilute copper sulfate for processing tomatoes, several factors must be taken into account. First of all, the specific disease plays a big role, since the dosage of the drug powder is different in each case.

That is why it is important to know the characteristics of each disease. It is also necessary to take into account the size of the area to be treated and the required amount of water for the solution.

Based on this, you can already draw conclusions about the required dosage.

Toxicity

Copper sulfate has a hazard class 3 for humans (can cause serious irritation of the mucous membrane upon contact with the drug or solution) and a hazard class 3 for bees (border protection zone for bees is 4-5 km). The drug has low toxicity for bees, however, it is better to isolate the bees during the period of crop treatment and for the next 5-20 hours. Not phytotoxic if dosage is not exceeded.

Security measures

Perform processing using gloves and goggles; avoid smoking, drinking, and eating while working. In case of contact with skin or mucous membranes, rinse with plenty of water; if it enters the digestive tract, vomiting usually occurs immediately, do not take any medications, call an ambulance immediately.

Every gardener’s plans include measures to prevent plants from fungal diseases . One of the most accessible means used for treatments is copper sulfate. The effectiveness of its use, instructions and rules for preparing a working solution against late blight will be discussed in this article.

Pros and cons of the substance

One of the most serious advantages of using this substance is its long duration of action; after treatment, plants remain protected for 1 month.

In addition, not only seedlings, but also the soil around them are affected by the drug, which makes infection with various pathogens and viruses virtually impossible. Copper sulfate works great against late blight on tomatoes.

The drug also allows you to cope with a large number of diseases and ailments, without the need to change the mixing proportions of the solution. It has a very broad effect, which makes it possible to protect seedlings and soil from virtually all types of threats.

In addition, the drug is low in cost and is available in virtually any specialty store, and tomatoes that have been treated with this substance can be eaten after a short period of time, which is very convenient. They also need to be washed thoroughly.

Unfortunately, there are also disadvantages to using copper sulfate for tomatoes. First of all, it is very difficult to determine the dosage on your own, especially if you do not have experience and relevant knowledge. In addition, if you exceed the required dosage, you can burn the bush.

Pre-preparation: the very first spring work in the greenhouse

In order for disinfection to be as effective as possible, the greenhouse must be prepared for this event. In this case, the starting work consists of several stages.

Stage No. 1. Freeing up greenhouse space

Remove from the greenhouse everything that prevents free access to greenhouse surfaces and interferes with sanitary processing. Inventory, shelving, side fences, cups for seedlings, pegs - in a word, everything that was safely stored here all winter, move to another place for a while. Also remove supports if you used them to support the roof in case of heavy snowfalls. Inspect all wooden structures thoroughly. If you find areas affected by fungus, replace them. Also carefully analyze metal elements for rust. For preventive purposes, the wood is treated with slaked lime, and the metal is painted after removing the rust.

Stage No. 2. We recycle garbage

According to the rules for caring for a greenhouse, all garbage must be removed and disposed of in the fall. However, if you didn’t have time, don’t miss this important stage in the spring. It is better to burn pieces of twine, roots of last year's plants, pegs, fabric scraps for tying and other disposable material. In this case, the resulting ash can be used as fertilizer.

Stage No. 3. Fighting the dirt

The walls of the greenhouse must be transparent so that the sun's rays penetrate through them. But if the film, glass or polycarbonate is covered with a layer of dust, there can be no question of any compliance with the light regime. To remove dirt, you can use a solution of laundry soap or special products. At the same time, inside the greenhouse, do not wash away soap and chemicals with a hose stream so that all this does not get on the soil. It is better to wipe the surfaces several times with a damp cloth.

And now, when the greenhouse has been cleaned, repaired and washed, you can begin to disinfect it.

How to treat the soil

No one will dispute the fact that it is in the soil that pests, nematodes and disease spores are found. Therefore, tillage is necessary. It has also been performed since the fall. You can treat heavily contaminated soil with a formaldehyde solution (40%). You cannot enter the greenhouse for three days, then you need to ventilate it for a day. To spray the greenhouse, a one percent solution of Bordeaux mixture is prepared. If the treatment is carried out in the spring, then a month before placing the plants in the greenhouse.

To destroy not only late blight, but also powdery mildew, bacteriosis, and tomato blight, calcium hydroxide is added to the Bordeaux mixture.

To cultivate soil in a regular bed, the composition of the copper sulfate solution is prepared identically.

Features of processing and prevention

During the growing season, tomatoes need to be sprayed three times with copper sulfate. This is done for prevention - which is always safer to use already at the stage of progression of fungal infections. As in methods of combating any other diseases, in order to protect yourself from pathogens, you should not wait for the outbreak of an epidemic. Prevention of a disease is always more effective than its treatment, no matter what means are used to combat it.

You cannot feel safe even if there are no foci of late blight on your site - after all, spores are easily carried by the wind, as well as on the soles of shoes or items of clothing.

Tilling the soil with copper sulfate in the spring is carried out in 4 stages.

1st stage

Treatment of tomato seedlings begins 2-3 days before sowing the seeds (not only the soil, but also the storage containers themselves are sprayed with liquid). The solution is prepared concentrated, 3%.

2nd stage

The prevention stage is diving, when young plants already acquire two or three leaves. Soil and containers from the store do not need to be treated - but your own, last year’s cups and soil, definitely require “disinfection”.

3rd stage

Root treatment before planting in open ground - regardless of the detection or absence of late blight on the site. You will need to pour a lot of copper sulfate into the wells (for each - 1 liter of a 1% bluish solution). Next, prepared soil and compost are added to the holes and left for a day. The next day, the soil is ready for planting tomatoes.

4th stage

Foliar treatment (spraying with copper sulfate of reduced concentration - 0.1-0.2%) is carried out for additional protection of young leaves of tomato bushes at the time of the first ovaries.

Important! Mixtures based on copper sulfate or other copper sulfates (Bordeaux mixture, zineb, etc.) are the most effective means of combating diseases and microorganisms affecting tomatoes. However, for humans, copper salts are a strong poison. There is no copper in the fruit, but processed tomatoes must be thoroughly washed before consumption.

Safety regulations

Copper sulfate is a chemically toxic substance that requires compliance with the following safety rules.

• Mixing solutions is allowed only in non-metal containers (optimally plastic).
• The solution cannot be stored for a long time. Its effectiveness decreases exponentially over time - 5-10 times after 4-8 hours and almost to zero after a day.
• During the process of using the solution, children and pets are not allowed to be near the site.
• Spraying requires the use of special sprayers.
• Do not work with the drug without rubber gloves, goggles and a respirator (or at least a face mask).
• Once you have finished treating the area, wash all exposed areas of your body, face and hands thoroughly with soap and water.
• Packages of copper sulfate must be stored in a dark, dry place inaccessible to children and animals.

Conclusion

1. Never forget to use compounds that protect your crops from pests and diseases.
2. Use them not only as a medicine, but also as a preventive measure.
3. Remember that copper sulfate is not only a remedy for many fungal diseases, but also an active fertilizer that promotes plant growth.
4. Never violate the dosage - using measuring containers, and not “visual acuity” and self-confidence in your own experience.
5. Be sure to strain the solution before use to avoid clogging the spray nozzles with incompletely dissolved crystals.
